TPA3116 5.1 Channel Digital Audio Amplifier Board, 4x50W + 2x100W, Professional Surround Sound System

Discover our 5.1-channel digital power amplifier board, built around four TPA3116 chips for exceptional audio performance. This board features a high-sensitivity input, allowing direct connection to your computer sound card, set-top box, DVD player, or HD player. It's also perfect for upgrading most existing AV amplifiers. It's easy to use and noise-free, especially when paired with a front-end power supply.

For superior sound quality, this board incorporates ruby electrolytic coupling capacitors, TDK CBB low-pass filter inductors, and large parallel filter capacitors. Compact, efficient, and energy-saving, it's ideal for building a mid-range 5.1 amplifier.

Its applications are varied: home theater audio systems, car speaker upgrades, or any other project requiring high power and excellent sound fidelity. It offers numerous practical features: ACC-controlled delayed start, control circuitry, power supply mute, external control switch, and external interfaces with LED indicators. It has 6 completely independent inputs and 6 outputs for a pure preamplifier. All terminals are made of pure copper with large holes for easy wiring and secure connections.

**Technical Specifications:**
